OSB

Oh Shit Bag. An emergency bag you keep in the back of your ride in case you end up in an emergency. Usually has roadside items, and a day’s worth of food, water, First Aid, and any other emergency you could face day to day. Pretty much a bag for when shit happens. Hence the “Oh Shit” part.

This is my OSB. I don’t touch it unless I absolutely need it.

OSB

An acronym for Oh Shit Button. Used in MMOs, OSBs are OGCD (off global cooldown) instant-cast heals that can be used when the tank unexpectedly takes a massive loss in health.

The tank stood in the telegraph and I had to use my OSB to keep them from dying.

OSB blanket

Sarcastic term for da infamous "government-surplus cheese" equivalent in da bedclothes-department --- i.e., da heavy rough scratchy deplorably-crappy grayish-purple "compressed and fused lint-balls" comforter dat da State doles out to indigent individuals/families during da colder months, and dat usually falls apart after just one season.

I can certainly see how ground-up-cloth-remnant blankets would indeed likely be comparatively cheap to produce, but real cloth is much sturdier and longer-lasting, and so it seems to me dat it would actually cost Uncle Sam less in da long run to give low-income folks actual-woven-fabric "layers of warmth" instead of those lousy-a** OSB blankets, since they would not have to keep being replaced with new ones so often.

OSBS

osbs means "on some bullshit." This is a shorter way to write it in text.

"you're really osbs, what are you even talking about?"
